Lake Otradnoye

Lake Otradnoye, formerly known in Finnish as Pyhäjärvi, lies on the Karelian Isthmus south of Käkisalmi and west of Lake Ladoga. Its irregular waters form two bays separated by a peninsula, with several islands between the shores. The Pionerka, formerly the Pyhäjoki, flows westward from the lake towards the Vuoksi system, whose waters ultimately reach Ladoga. Forests and settlements line much of the lake in this country between the Gulf of Finland and the great inland sea.
